title: [Characterization of genetic EEG-variations with the amplitude-interval-analysis. I. Variations of alpha-activity; flat-EEG; borderline flat EEG, occipital slow beta-waves; monotonous alpha-rhythm (author's transl)].
abstract: In 121 healthy adult male probands with different variants of alpha-activity (monotonous alpha-waves; low voltage EEG, borderline low voltage EEG; occipital slow beta-waves) a quantitative description of unipolar leads was carried out using a program for amplitude-interval (time-domain) analysis. Statistically significant differences between means of the examined parameters were discovered between the various EEG variants. No single parameter, however, separates these variants reliably. For such a separation, methods of multivariate statistics will have to be used. Significant differences between right and left hemispheres (primarily lower alpha-activity together with higher beta-activity on the left hemisphere) were found in all EEG types examined except the variant with monotonous alpha-waves.
